WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
Make sure that there is a hydrogen peroxide concentration of
around 0.5 ... 0.8 mg/l in the pool to be able to calibrate the sen‐
sors.
Example (without depletion losses): A swimming pool contains 60
m

, by way of example. To obtain a hydrogen peroxide concentra‐
tion of 0.5 ... 0.8 mg/l in this swimming pool, requires 0.20 ... 0.32
litres of 30% hydrogen peroxide (density (ρ) 1.11 ± 0.02).
Meter in the required quantity of hydrogen peroxide into the
filtration circuit, either using the hydrogen peroxide metering
pump or evenly distribute the quantity of hydrogen peroxide
needed into the swimming pool using a measuring cup

An even concentration can be expected once the reac‐
tion time has elapsed:

User qualification: instructed user, see
Display tolerances
Display tolerances between the sensor and/or
measuring device and controller have to be cali‐
brated with sensors and/or with output signals of
measuring devices that do not require calibration
or where calibration is performed in the sensor/
measuring device. The relevant information for this
is contained in the respective operating instruc‐
tions for the sensor or measuring device.
